VMware Consolidated Backup（VCB）的使用

 

VMware Consolidated Backup（VCB）的使用（一）

VMware Consolidated Backup是VMware为VMware Virtual Infrastructure新推出的一款备份工具，操作简便、功能强大，但代价不菲，需要ESX和VCB Proxy同时连接到共享存储SAN！（在写本文时实验环境是直连的SCSI盘柜，可简单看做SAN。NFS、ISCSI未经测试）

拓扑结构：

实验环境：ESX Server 3.0与VCB Proxy均为两台IBM X345服务器，1G RAM、36G HD、板载Intel双千兆网卡，连接到了一台Edins 3000 的SCSI盘柜上（RAID 5，容量只有200G，全部被ESX格式化成VMFS 3.0）

ESX服务器IP地址为192.168.19.124，在Edins 3000存储上随意安装了一台Windows 2003的虚拟机，装好VMware tools，ip地址192.168.20.101（就备份它了）

VCB Proxy安装Windows Server 2003企业版，ip地址192.168.19.247

ESX Server能完全管理到Edins 3000上的全部磁盘空间，Windows 2003的磁盘管理器只能显示出该磁盘，但无法有效管理。

1.首先在VCB Proxy上安装VMware Consolidated Backup，下载地址请自行搜索:-)

2.进入VCB Proxy命令行下，输入

C:\Program Files\VMware\VMware Consolidated Backup Framework>vcbMounter.exe -h 192.168.19.124 -u root -p 密码 -a ipaddr:192.168.20.101 -r e:\back -t fullvm -m san                                             

参数大概意思是需备份的ESX Server为192.168.19.124，使用root用户和其密码，预备份虚拟机Guest OS的ip为192.168.20.101，备份到e盘的back文件夹里，模式为全备份

其他参数可以运行 vcbMounter.exe 得到详细的说明

此时虚拟机可以是开机状态

以下为输出结果：

3.查看E:\back，证实备份成功。

VMware Consolidated Backup（VCB）的使用（二）

本文接 上篇

首先用 WinSCP3，把VCB Proxy的E:\back\文件夹里的内容都拷贝到ESX Server /tmp/back下

开始搞破坏喽-__-

首先请先关掉你正在运行的那台虚拟机，用VMware Virtual Infrastructure Client登录到ESX，删除与该虚拟机有关的所有文件！！模拟出来的灾难够严重的了吧:-)

如果此时尝试开启虚拟机，会得到错误提示：A general system error occured: Internal error

现在在Windows下使用 putty远程管理ESX，或者直接在ESX本地操作Service Console

输入：

[root@a2 /]# vcbRestore -h 127.0.0.1 -u root -p 密码 -s /tmp/back -b overwrite
注意vcbRestore的大小写

输出结果：

[2006-09-15 08:32:12.030 'App' 3076444288 info] Current working directory: /

        **************************************************                                        

[root@a2 /]#                                                                                                                         

再尝试启动虚拟机，无报错，进入系统后查看无异常，恢复成功！
